The most important holiday in spring, especially for Christians, is Easter. This Christian holiday is not on the same date every year，but it’s always on a Sunday. It can be any Sunday between March 22 and April 25. Many people celebrate Easter by buying new clothes. Children celebrate by hunting for colored eggs that their parents have hidden around the house. People also give Easter baskets filled with candy and other goodies to one another to celebrate the day.
But the holiday is more than new clothes and good things to eat. On Easter, many people go to church to celebrate Jesus’ resurrection（复活）from the dead. Most people color Ester eggs. Some people hide them. Others just eat them. But no matter what one does with Easter eggs，they are an important Easter tradition across the Western world. People from many different cultures celebrate Easter. In both America and Belgium, children look for Easter eggs hidden on grass and in bushes(灌木丛). In America, children believe the eggs are hidden by the Easter rabbit.But in Belgium, the hidden eggs are supposed to have fallen from church bells. In Bulgaria (保加利亚), red Easter eggs are lucky in churches. Bulgarian families also hit these Easter eggs together to see whose is the strongest. The winner looks forward to good fortune(运气) that year. Still dozens of other Easter traditions exist. In parts of Austria，for example，children sing from door to door and are rewarded with colorful eggs.
